Polyurethane foams that are hydrophilic but nonetheless have low compression sets are made from a combination of MDI and TDI prepolymers, water, and a polymer polyol. The foams optionally are made incorporating a phase change material in the foam formulation. The phase change material does not require encapsulation.

Polyurethane foams for comfort applications

Hydrophilic composite structures are made by impregnating a 3DL structure with a polyurethane foam formulation and curing the formulation to produce a foam that occupies the spaces in the 3DL structure. The composite structures have an unusually good capacity for retaining water even when under compressive forces. They also exhibit at most moderate swelling when saturated with water. The foam is useful as a layer of a water containment system such as a green roof or blue roof system.

Hydrophilic composite

Hydrophilic polyurethane foam is made from a diphenylmethane-based quasi-prepolymer having specified isocyanate and oxyethylene contents. The foams have an unusually good capacity for retaining water even when under compressive forces. They also exhibit at most moderate swelling when saturated with water. The foam is useful as a layer of a water containment system such as a green roof or blue roof system.

Hydrophilic polyurethane foam for water

Flexible polyurethane foams are made by reacting a hydrophilic quasi-prepolymer, water and a polymer polyol in the presence of a silicone surfactant and an ethylene oxide/higher alkylene oxide block copolymer. The foams exhibit desirably low densities and compression sets, and have good thermal and moisture-wicking properties. The foams are useful in bedding and other comfort applications in which they are exposed to body heat and bear at least a portion of the weight of the user. The thermal and moisture wicking properties contribute to perceived comfort for the user.

Disclosed are polymeric compositions with improved breakdown strength. The polymeric compositions contain a polyolefin and a voltage stabilizing agent, which is selected from one or more of a group of three specific triazine compounds. The present polymeric compositions exhibit improved breakdown strength when applied as an insulating layer for power cable.

A polyurethane gel for comfort applications includes a reaction product of a composition that includes (1) from 5 wt % to 35 wt % of a prepolymer component, based on a total weight of the composition, the prepolymer component including a reaction product of an isocyanate component that includes diphenylemethane diisocyanate (MDI) and a polyol component that includes a polyoxyethylene-polyoxypropylene polyol that has an polyoxyethylene content greater than 65 wt %, based on a total weight of the polyoxyethylene polyoxypropylene polyol, and (2) a remainder of a prepolymer-reactive component that includes an amine-terminated polyol and a propylene oxide-ethylene oxide based monol or polyol. The composition excludes any plasticizers.

Polyurethane based gel composition

A polyurethane foam for comfort application, includes the reaction product of a first composition that includes from 20 wt % to 80 wt % of an aqueous component and from 20 wt % to 80 wt % of a hydrophilic isocyanate-terminated prepolymer component. The aqueous component includes at least 90 wt % of water based on the total weight of the aqueous component and the hydrophilic isocyanate-terminated prepolymer component has a free NCO content from 1 wt % to 15 wt % and is a reaction product of a second composition that includes an isocyanate component and an isocyanate-reactive component. The isocyanate component includes at least 90 wt % of methylenediphenyl diisocyanate (MDI) and a weight ratio of 4,4'-methylene diphenylisocyanate isomer to 2,4&#x2032;-methylene diphenylisocyanate isomer greater than 1:1 and less than 10:1, the isocyanate-reactive component including polyethylene glycol and a polyoxypropylene-polyoxyethylene polyol having a molecular weight of from 3000 g/mole to 7500 g/mole and a polyoxyethylene content of at least 50 wt %, and the hydrophilic isocyanate terminated prepolymer component having an polyoxyethylene content from 45 wt % to 75 wt %, based on the total weight of the second composition.

Hydrophilic prepolymer for polyurethane foams

Bioelectrodes, methods of making bioelectrodes and methods of using bioelectrodes are provided. The bioelectrodes have an electrically-conductive substrate coated with an electroconductive polymer. The bioelectrode exhibits ohmic behavior over a range of about 1 Hz to about 100 KHz, where ohmic behavior means that the value of the impedance is independent of the signal frequency over the range of interest. The bioelectrode can transmit or receive an electrical signal between the electrically conductive substrate and the biological component through the conductive polymer.
